Title: Valve of the kind intended to be mounted within the bottom portion of a container
IPC: B65D90/62
Filed: 1975-10-29
Abstract: 1494864 Valves GUSTAV F GERDTS KG 29 Oct 1975 [4 Dec 1974] 44548/75 Heading F2V A cylindrical closure part 5, co-operating with a valve seat 4 of a valve controlling an exit 3 from the bottom 1 of a container, has a valve seat 6 for a closure part 7, both closure parts 5 and 7 being operated by a common actuating spindle 16 and biased to the closed position by a spring 24. The valve is used for a container filled with a load material which is brought by heating to a flowable condition and, if on actuation of the valve the load material has solidified around the valve seat 4 preventing the closure part 5 from opening, the load material can reach the exit 3 by flowing between the seat 6 and the closure 7 and through a flow channel 13. This flow of material would heat up and soften the solidified load material and allow the closure part 5 to open and the rest of the contents to reach the exit 3. A guide cap 11 is connected to the closure part 5 via webs 12 and is slidably mounted on a guide cylinder 9 which is connected by webs 10 to a valve mount 2. The actuating spindle 16 travels within the guide cylinder 9, has a guide collar 23, is slidable through a bore 33 of the cap 11 and is positively connected to an end wall 18 of the closure part 7. A spring 26 acting between the collar 23 and the cap 11 provides the necessary biasing force to open the closure part 5 when solidified load material has loosened. Stops 29, 30 ensure that the closure part 7 is still open when the closure part 5 is fully open. A bellows element 20 is provided between the closure part 7 and the guide cap 11 to prevent damage to the spindle by load material. Since closure part 9, guide cap 11 and guide cylinder 7 are effectively closed upwardly, air cushions form in spaces 21, 15 and 27, respectively, to help prevent contact of load material with the moving parts of the valve.

Patent GB-1157897-A (GB)
Title: Valve Assembly for a Fluid Intensifier
IPC: F15B11/15
Filed: 1966-10-10
Abstract: 1,157,897. Valves. HUCK MFG. CO. 10 Oct., 1966 [23 Oct., 1965], No. 45256/66. Heading F2V. Pressure signals, for actuating a rivet installation rod, are derived from passages 30 and 32, connected to a supply not shown, in response to reciprocation of a piston 26 formed on a shaft 24 connecting two further pistons 20 and 22, the latter pistons being pneumatically actuated. Within a housing 12 there are formed two cylindrical cavities 14 and 16 interconnected by two bores 17 and 18, the first being axially situated and containing the piston connecting shaft 24, and the second being axially offset and housing a valve 42. The valve comprises a fixed housing member 44 and, movable within it, a closure member 86. Two annular grooves 128 and 130 formed within member 86, are arranged to connect either one of ducts 60 and 64 with duct 62 and either one of ducts 64 and 68 with duet 66 respectively, all ducts being formed within the housing. Ducts 60 and 68 are permanently connected to exhaust through lines 72 and 74, whilst duct 64 is similarly connected to a pressure line 76. Thus, in the position shown, exhaust 72 connects, via duct 60, groove 128, and duct 62, with line 40 which opens into the two cavities 14 and 16, and pressure 76 connects, via duct 64, groove 130 and duct 66, with line 38 which likewise opens into the two cavities. As a result the pistons 20 and 22 are caused to move in unison downwardly. Towards the end of this movement, the upper piston 20 strikes the stem 92 of a piston 96, housed within the closure member 86 and biased by a spring 98 against a stop 100, with the result that the piston is moved downwardly until a sufficient force is built up to move the closure member out of its position shown and into its lowermost position, this force being necessary to overcome the resistance to movement provided by detent means 116, the means comprising a ball and cap 120 and 124 biased by a spring 126 into engagement with either one of two grooves 112 or 114. Thus, when the closure member is moved into its lowermost position, as determined by the registry of ball 120 with groove 114, the pressure line 76 is connected to line 40 and exhaust 74 to line 38 thereby reversing movement of the pistons 20 and 22, with further reversal occurring when piston 22 strikes stem 102.

Title: Method and apparatus for the distillation of spirit
Inventor: THOMAS DUNCAN GROVER
IPC: B01D3/00
Filed: 1965-10-27
Abstract: 1,091,589. Control of distillation; manufacture of whisky. LITTLEMILL DISTILLERY CO. Ltd. Oct. 24, 1966 [Oct. 27, 1965], No. 45443/65. Heading B1B. The rate of distillation of whisky wash in still 1 is automatically controlled by pressureresponsive device 16 and controller 17 which maintain the pressure in the still at an appropriate value by adjusting the quantity of heat supplied to heating element 2; and the condensate from condenser 7 is automatically collected in either whisky storage tank 14 or reject liquor tank 15. As shown, the still comprises a fractionating column 3 and a dephlegmator 4; and temperature-sensitive element 13 controls three-way valve 10 so that the distillate is collected in tank 14 or tank 15 in accordance with the temperature of the vapours leaving the still. The heating element 2, which comprises a main part and a booster part, may be steam-heated. As the boiling point of the wash is approached, the booster part is cut out, and the heating is continued by the main part of the element 2 alone. At the appropriate pressure, e.g. 2lb./sq. inch gauge, the quantity of steam supplied to the main part of element 2 is reduced by controller 17. The amount of reflux is controlled by automatic controller 5 which adjusts the flow of cooling water through dephlegmator 4. Meter 8, which measures the specific gravity of the distillate, is connected to valve 10 and can alter its position to direct the distillate into tank 14 or tank 15. The element 13 and the meter 8 act in series; i.e. if one device signals that the distillate is to be rejected, then it is rejected regardless if the other device signals to the contrary. Element 13, or meter 8, signals to controller 17 when the quantity of spirit in the still has been reduced to a predetermined quantity, and valve controlling the steam supply to heater 2 is shut off.

Title: Fail safe controller
IPC: H02H5/04
Filed: 1966-10-12
Abstract: 1,134,879. Transistor switching circuits. TEXAS INSTRUMENTS Inc. 12 Oct., 1966 [21 Oct., 1965], No. 45566/66. Heading H3T. [Also in Division H2] A fail safe protective arrangement, e.g. for a motor, includes a voltage divider connected across a high impedance secondary winding 13 of a transformer T1, the voltage divider comprising a reference impedance, e.g. a resistor R1 and a variable impedance sensing device X1 e.g. a positive temperature coefficient resistor embedded in the motor winding. A transistor Q2 has its emitter connected to a tapping 14 on the secondary winding 14 and its base to the junction between the impedances R1, X1. A silicon-controlled rectifier Q1 is connected in series with a load, e.g. a relay coil RYK, and has its cathode gate circuit connected to the collector of the transistor Q2 and to the end of the device X1 opposite the junction. Normally, the impedance of the device X1 is low so that the transistor Q2 and rectifier Q1 are conducting and the relay RY is energized to close its contacts RYA, e.g. to energize a contactor in the motor supply circuit and to open contacts RYB to connect a resistor R2 in series with the voltage divider to increase, the operating differential. When the impedance of the device X1 increases, e.g. due to overloading of the motor, or should the device X1 become opencircuited, the transistor Q2 is cut off so that the triggering pulses to the rectifier Q1 cease. The rectifier Q1 ceases to conduct and the relay is de-energized. Should the device X1 become short-circuited, there will be virtually no voltage applied to the gate of the rectifier Q1 which ceases to conduct. The rectifier Q1 may be connected directly in series with the protected load. A plurality of voltage dividers may be provided, each divider having a respective sensing device and an associated transistor. The emitter-collector paths of the transistors are connected in series and control a single controlled rectifier, Fig. 2 (not shown). These arrangements may be modified so to permit the use of negative temperature coefficient resistors or PNP transistors.

IPC: H04L25/49
Filed: 1967-10-06
Abstract: 1,214,324. Digital facsimile transmission systems. PLESSEY TELECOMMUNICATIONS RESEARCH Ltd. 4 Oct., 1968 [6 Oct., 1967], No. 45893/67. Headings H4F and H4P. In a facsimile transmission system a binary signal, representing the black and white image and generated by the scanner, controls a modulator, each transition in the signal changing the level of the modulated signal in the same direction. In a first embodiment the binary signal controls a multi-level generator to produce a multi-level amplitude modulated signal in which adjacent levels represent different bit states and in which each change in level is in same direction as the previous level change if the number of bits between these transitions is less than a preset number, but is in the opposite direction if the multi-level signal is currently in the highest or the lowest permitted level. Further, if a transition occurs between two runs each having more than the preset number of bits the change in level is towards a chosen one of the highest or lowest levels or one of the levels adjacent these: as described the change is towards the highest or the next highest level. If a transition occurs after a run having more than the preset number of bits but before a run having less than that number, the level change is in the direction of the larger number of levels needed to reach the highest or lowest level. The system described thus attempts to maintain long bit-runs on the highest two levels, so allowing as large as possible a number of adjacent short runs (representing fine image detail) to be transmitted over a narrow band channel without the distortion that results when adjacent short runs occur on the highest or lowest levels. The circuitry described includes means for detecting discrepancy between the binary level represented by the transmitted signal and the binary level from the scanner and for inserting an additional change in the transmitted level in such a case. In a second embodiment, Fig. 4 (not shown), each transition in the binary signal from the scanner shifts the phase of a carrier in the same direction and by an amount equal to 360 degrees/2n where n is an integral greater than 1.

An audible and/or visible alarm 5 indicating failure of one or more stop lamps L in a road vehicle is controlled by a high current circuit completed when a switch S is closed to light lamps L or a low current circuit through Y or R4 passing insufficient current to light lamps L. In Fig. 1, when S is closed and a lamp L has failed, a relay R1 is de-energized, contacts C1 are closed, a relay R2 is energized, contacts C2<SP>1</SP> are closed, and the alarm is operated. If switch S is opened the alarm is operated through relay contacts C3 on failure of a lamp L. Relay R3 is protected from overvoltages; switch S is closed by normally open contacts C2. Alternatively, a switch ganged to switch S may close contacts C2<SP>1</SP> and open contacts C2, thus rendering relay R2 unnecessary. In a further arrangement (Fig. 2, not shown), stop lamps L are connected via a diode gate to the base of a transistor which conducts to operate alarm 5 when a lamp has failed. The low current circuit is de-energized when the high current circuit is energized by a relay (R1) having contacts (C1) in the low current circuit. In Fig. 3, lamps L are connected to the alarm 5 through a NAND gate T2-T5. In all arrangements, an alarm test switch Sl is provided, controlled by the starter switch.
